Room-temperature phosphorescence (RTP) is a photophysical phenomenon typically associated with long-lived emission that can be detected by the unaided eye. Several natural proteins display RTP, as do certain artificial polymers. In both cases, RTP ascribed to effective intramolecular through-space electronic communication. However, small molecules internal communication enable are relatively rare. Herein, we describe an alkyl halide-responsive system consisting of meta-formylphenyl-bearing pillar[5]arene derivative supports charge transfer (TSCT) within pillararene cavity. Treatment bromoethane, heavy atom-containing guest for host, serves enhance emission. An isomeric para-formylphenyl-bearing proved ineffective in producing effect. Quantum chemical calculations based on single-crystal X-ray diffraction analyses provided insights into structural determinants governing TSCT between 1,4-dimethoxybenzene donor units and formylphenyl groups pillar[5]arene, well energy gaps intersystem crossing channels. We believe present mechanistic analysis provide foundation design new molecule tunable features.

Purely organic room-temperature phosphorescence (RTP) materials have received intense attention due to their fascinating optical properties and advanced optoelectronic applications. The promotion of intersystem crossing (ISC) minimalization nonradiative dissipation under ambient conditions are key prerequisites for realizing high-performance RTP; However, the ISC process is generally inefficient fluorogens populated triplet excitons always too susceptible be well stabilized by conventional means. Particularly, organizing fluorophores into compact ordered entities supramolecular dynamic interactions has proven a newly-emerged strategy boost greatly suppress non-radiative relaxations immensely, facilitating population stabilization access RTP. Consequently, well-defined emitters enable robust RTP emission even in solution state, thus extending Here, this review focused on timely brief introduction recent progress tailoring interactions. Their typical preparation strategies, properties, applications thoroughly summarized. In summary section, challenges perspectives field highlighted suggest potential directions future study.

Molecular emitters with multi-emissive properties are in high demand numerous fields, while these basically depend on specific molecular conformation and packing. For amorphous systems, special arrangement is unnecessary, but it remains challenging to achieve such luminescent behaviors. Herein, we present a general strategy that takes advantage of rigidity S

Abstract Polyethylene glycol chains in two terminals of the naphthalene functional group are threaded into α‐cyclodextrin cavities to form pseudopolyrotaxane (NPR), which not only effectively induces phosphorescence by cyclodextrin macrocycle confinement, but also provides interfacial hydrogen bonding assembly function between polyhydroxy groups and waterborne polyurethane (WPU) construct elastomers. The introduction NPR endows elastomer with enhanced mechanical properties excellent room temperature phosphorescent (RTP) emission (phosphorescence remains water, acid, alkali, organic solvents, even at 160 °C high temperatures). Especially, reversible mechanically responsive behavior intensity increased three times under 200% strain) can be observed stretch recover process, owing strain‐induced microstructural changes further inhibiting non‐radiative transition vibration NPR. Therefore, changing supramolecular elastomers through stretching a new approach for luminescent materials.
